Not sure how you determined "good" battery.

Check battery with a DMM, all lights and accessories off and no charger. A reading less than 12.3 VDC indicates failing or under charged battery.

may sound like a dumb question but you didnt by chance hook up the battery or jumpstart the car with polarity reversed by accident at some point during this process? i would check all the underhood main fuses and interior fuses as well, what is the condition of the battery post clamps? if they are badly corroded be sure to clean them very well and wash them with a baking soda and water solution im thinking one of the cables or smaller wires that hook up at the battery is broken or possibly some freak accident happend and the computers need to be flashed at a dealer. either way i wish you luck please rate -jeff

Not trying to steal your solution, but trying to clean up the unanswered page:
There are two possible answers here:
The simple one: Use your remote control's "unlock" button to reset the anti-theft system.
or a more comlex one that seems to work: (From the original post)"I found out that you remove the horn fuse, shut the doors, put the key in and unlock it two times then put the fuse back in...it resets the anti theft..."

take the positive side of the battery off for about 3 seconds and then put it back on to see if this will reset the security code

SOURCE: anti theft dash light is blinking on my 1998 rodeo

I'm assuming its an original alarm or system that came from factory or dealer. When the light blinks is because the alarm is activated. Look underneath the radio the alarm brain might be there. There will be a label on it saying alarm or security system etc. Disconnect the harness to it and try operating your vehicle.

Theft light on car won't start , hook a battery charger up to your car to maintain a good charge . Then turn ignition to on position , do not crank it over leave in that position for ten minutes then turn to off and repeat this cycle two more times .
After the third time turn to off and remove key from ignition then ,
reinstall key and try to start vehicle if it works you just relearned your key to the anti theft system and you gain a free lesson !!!

Replace the battery in the remote, then reset the system.

Resetting a Vehicle Anti-Theft System
This is how you reset an anti theft system if you have the anti-theft light on, or your car is cranking, but you have no spark.

Doing a full reset of the anti-theft system.

Disconnect both battery leads for at least two hours.
Hold the negative and positive leads together for 5 minutes to fully discharge any power.
Put the key in the ignition, but not turned on. VERY IMPORTANT!
Connect the positive lead.
Connect the negative lead in one swift movement.
Wait 15 minutes for the system to fully reset.

if the security light is flashing than the anti theft is active. The anti theft shuts down the injectors and will not let the vehicle start.

You'll need a battery charger to do this. Hook up the battery charger to the battery.

Place the key in the igniton and attempt to start. Let the key return to the run postion and leave it there untill the light stops flashing. Turn the key off

Turn the key on (do not try to start) and wait for the light to stop flashing again.

turn the key off and then try to start the vehicle.

You can google search "resetting gm security" and find this info as well.

to turn off the theft system, all you have to do is put the key in the door lock and lock and unlock the door, this shuts down the anti theft system,now this has nothing to do with the radio, the only way the radio would ask for the code is if it was removed or the battery unhooked,anyway try the unlocking of the door even try the passenger door, hope this helps.
